1959: Hydrox Ad Looks Yummy

Hydrox was not an Oreo knockoff and in fact appeared four years before Oreos did. Apparently the name came from Hydrogen and Oxygen, the two molecules in water, which doesn’t make a lot of sense to me since the cookies have nothing to do with water. I mean, you’d never even dip them in water. But it was cool to sound scientific in 1908, I guess.
